FIELD: information technologies.
SUBSTANCE: invention may be used in devices that operate in DVB-T standard and other broadband systems using COFDM-modulation. Algorithm is used, which makes it possible to increase speed of correcting coefficients convergence, and to eliminate operations of division and Fourier inversion in process of their calculation.
EFFECT: improved efficiency and accuracy of recovery of frequency characteristic of channel under conditions of symbol-to-symbol interference.
